Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

Some optical properties of neutron diffusion waves are discussed. Expressions are given for the change in the direction of propagation of the wave components reflected and refracted at the interface between two semi-infinite media by using appropriate formulae for the refraction of the electromagnetic waves in conducting media. It was found that the phase speed of the refracted asymptotic wave depends upon the direction of propagation. This dependence is especially noticeable in graphite/light-water systems. The phase speed is practically constant in graphite/ heavy-water systems. The results predict the existence of the total reflection of the asymptotic wave on the graphite/vacuum interface, providing the incidence angle is larger than ∼23°. Experimental verification of the diffusion wave refraction is suggested.
